Mixability in Statistical Learning

no code implementations NeurIPS 2012 Tim V. Erven, Peter Grünwald, Mark D. Reid, Robert C. Williamson

We show that, in the special case of log-loss, stochastic mixability reduces to a well-known (but usually unnamed) martingale condition, which is used in existing convergence theorems for minimum description length and Bayesian inference.

Adaptive Hedge

no code implementations NeurIPS 2011 Tim V. Erven, Wouter M. Koolen, Steven D. Rooij, Peter Grünwald

In most previous analyses the learning rate was carefully tuned to obtain optimal worst-case performance, leading to suboptimal performance on easy instances, for example when there exists an action that is significantly better than all others.
